Help us with English (British) forum software translations

[webwit]

We use a modified version of the phpBB forum software. phpBB offers various translation packs, and we have various of these installed. However, our custom mods and additions are not covered by these packs, so this is where we need your help.

English (British) is the default language, so no translations are needed.
You can use this topic though for for additions, corrections and improvements.
