Finally had time to do a few updates to this (am planning on a complete re-write). Updates to this include;
* Corrected missing CSS spec in config.php
* Renamed var used for whitelist check, to stop clash with existing var
* Various bug fixes in index.php, check_spammers.php, check_spammers_plain.php, functions.php
+ Check to ensure StopForumSpam API key is present
It is still in need of a logo (doesn't currently have one, and I'm not a graphics person (as those that know me will attest ;o) ). I am contemplating running a competition to have one of you chaps and chapesses design one, but aside from their currently being a competition (ends October 31st), I am unsure as to what to give away for it (hints welcome folks!).
You can find the updated SBST in the usual places;
Please let me know if you notice any issues (or indeed, anything that can be improved).
