The change was made on the 12th, however the scripts do not compile even with the current svn. I did read the first page, and did wait until the addition was made... however, it does not compile with the current sourcemod build. This may not have anything to do with your script, and as I said, I've asked baliopan to check on why it is not compiling.
If you have any additional information that would assist us in finding the problem, that would be wonderful.
Thanks
EG, what did you add besides the DialogType_AskConnect?
Was anything else required to get the dialogtype defined?
