Accessibility

HTML documents are said to be accessible if they are optimised for users with physical disabilities, and are compliant with a variety of software and hardware configurations. The pages on this site have been tested for accessibility and standards-compliance using software tools designed for the purpose. Where shortcomings were indicated by the tests, we have verified that the effects are minimal. However, we advise that you use a screen with a resolution of at least 1024 pixels in width, and a browser which runs JavaScript 1.2 and HTML 3.2. Most 'modern' and 'main-stream' browsers will suffice, but specialised text-only browsers (especially those that do not recognise HTML Tables or Cascading Style Sheets), or browsers running within an arcane operating system may not be suitable for reading these pages.
 

Visually-impaired users should note that you can specify the font sizes, styles and colors, and foreground and background colors of web pages displayed on your computer screen, even if the author of the page has already specified these. You can also specify the colour used to indicate links in web pages, or a special colour for links that is used only when the mouse passes over the link. This is useful if you have low vision, need larger fonts, or need high-contrast colors.
 

Some pages on this site require JavaScript to be enabled within your browser. (See further information on JavaScript).
 

Access Keys

Access keys have been defined for the new-style pages on this site to enable you to navigate using the keyboard shortcuts shown in the list at the foot of this page. (The old pages on this site will be gradually updated during 2006). Additionally, your browser probably has shortcut keys for back (try alt left-arrow), forward (alt right-arrow) and home (alt home).
 

The Access Keys facility is only supported by MS Internet Explorer 4 and above and by Netscape 6x versions. To use the facility, press the ALT key and, simultaneously, the access key number or letter. Release the keys and then, with some browsers, you need to press the RETURN key. With Macintosh-based systems you should use the CTRL key instead of the ALT key.
 

File Formats: viewing and downloading

Some documents on this site are stored in Adobe Portable Document Format (PDF) or Microsoft Word format. These file formats are used to store documents with complex formatting that the authors would like to preserve (typically text in several columns and mixed with a number of graphics). Some documents may be compressed using WinZip.

PDF: To view and print PDF files, you must have a PDF reader installed. Adobe Acrobat PDF readers are available for download for most computers from adobe.com/products/acrobat. If you are a RISC-OS user you could try this link or do a Google search. GNU/Linux people might like to use evince, xpdf, gpdf, or kpdf, or try this Google search.

WORD: Microsoft Word viewers and converters are available from office.microsoft.com/downloads/.

ZIP: You can download WinZip from winzip.com.

Data Protection Policy

(1) BCA will guard the data of its members, subscribers and other customers in accordance with the Data Protection Act (1998) and its Schedules. Personal data shall be obtained only for the specified purposes of i) administering membership, subscription and sales services and ii) mailing of items solicited by its customers. Data will not be disclosed to any third party nor used for any purpose other than those stated above without the express consent of the customer. Data may be stored at more than one location and may be stored on paper and in computer files.

(2) Email addresses may be stored by software applications such as phpBB and mailman for the purpose of administering web and email forums to which the customer has opted to subscribe and by such action indicated his agreement to any stated or implied terms and conditions. Where such software applications issue or require passwords the user is expected to be familiar enough with these software applications (which are widespread throughout the Internet) to understand the consequences of such passwords being weak and transmitted en clair.
