I would like to say, this is the BEST forum service I've EVER used. Reasons:
-Helpful Support
-No Advertisements/spam
-Its FREE!
-A wide variety of styles.
-Easy to use interface.
-No bandwidth limit.
I have one suggestion, as stated by someone else, I think the only thing to suggest to you is to NOT change anything unless its adding a feature or something. I have seen NO bugs whatsoever in my time so far using the forum. You are doing an absolutely amazing job! Keep it up.
[Off-Topic]There is one thing, I would like to add some kind of instant messenger or chat, other than PM, but I have No clue how
[/off-topic]Thanks for your service,
