I'm generally not one to bitch about such things, but please look at the following picture. I'm sure you can agree that the ads are a little bit of overkill. Could we either have them immediately following the OP or at the end of the replies? Eg not both?
I'm a fan of you folks advertising on your site (I mean, duh), but I'm not a fan of ridiculous overkill...which is what this comes across to me as (eg annoying). I'm pretty sure you'll agree with me if you are active on the forums. If you want to reach folks that post on the forums a lot, then an ad after the last post is best (though annoying). If you just want to throw out some info to folks that read the op and move along, then after the OP is best. I think after the OP is the best call. Thanks!
