Thanks for the suggestions - glad you like it the way it is now
Not particularly keen on advertising to be honest. I don't generally run forums that way. Also, I like small communities, especially when I don't have to get a dozen idiots asking for help each day. So far, pretty much everyone who's posted here is well informed and support requests are more because of my lack of explaining things, rather than people not knowing how to upload.
However, you're free to do what you want, so if you want to do it, I have no complaints.
Thanks for the pointer Harry. TBH, I'm not terribly interested in MyBB in general anymore than I need it to run my forum, but if he's interested, he's welcome to make suggestions here as well.
