It's discouraged for them to offer to do that. There are so many helpful threads that teach how to do things on the forum, if they want to participate it wouldn't be hard for them to do a search and find the answers to whatever "how to" is confusing to them. Also, every one of us mods is always more then willing to help a confused member learn how to do what they can't figure out.
The reason we have these limits set is to encourage participation on the forum. You get what you give, kinda thing. If one person doesn't take the time to learn how to post an attachment and offers to email, they may email to our regular incredible members, but they also may email it to people that come to download the templates and never participate. Plus, I'd have to question how great the template is if they can't even figure out how to attach a file here.
