It's not very feasible. Not all new members who register here intend on posting, let alone viewing, the BMX section - by far.

To know which ones were going to post here, we'd have to let them make at least one post or thread, and I don't really think we can make a script to do that effectively. Think about it, if it automatically sent the PM to members who made their first post here, what about if they made a post somewhere else first, and their post count was over 1? We'd have to do it manually, and that's a lot less welcoming than a friendly (or not so friendly, even, but personal) reminder to type properly, search, etc.

Most members who will cause trouble will be too impatient to read anything before they post. That includes stickies, rules, other posts, using the search function (most of the time), or probably even PM's. That's the problem with stickying this thread; there's already one with a similar title up there, with slightly different information, and I doubt most of them would read both. I don't, when I sign up to a new forum, but I've been on various forums for over 5 years and don't type like an idiot anywhere.
