i buggered up my comments for the last few days - incase anyone was wondering why they weren't working (i just thought nobody loved me - i should have guessed something was up by the lack of comment spam!).
update: i thought i'd catalog here for future reference what the problem was, seeing as i couldn't find a solution through google, but had to figure it out for myself (not that it was that difficult)...
the error i was getting was something like this:
Invalid [] range "l-e" in regex; marked by <-- HERE in m/ http://xxx.org/#viagra|-casino|-com.com|-xx-xx.org |-xxx.com|-xx.net|-xx.|-xx.info|.+xxx.+os.com |.+xx.com|.xx.ro|.xx.ro|0 at extlib/jayallen/Blacklist.pm line 3098.
and the reason i was getting this error was because i had added a url containing a square bracket to my blacklist of 'disallowed' urls - can't remember if it was right or left - but one of these: ], [
so, after much consternation and head scratching, i remembered that i could edit the list of urls from an interface (mt-blacklist.cgi - that was provided with the blacklist plugin that i had completely forgotten about). so i removed the offending url and everything worked fine again. and so it goes.
Yep writing comments and then getting messages back with all sorts of medication was interesting, if you are using movabletype talk to me about a captcha system i have installed on my site works a treat. Oh damn forgot great shot as always, shows of the skyline of Dublin perfectly at the moment.
BTW congrats on getting to picture 700 oh my god.
