I sometimes feel that way about my welcome messages, too.
Give them the gist of what SFI has to offer, but throw in some humor and a few one-liners. Just make sure not to be crude or vulgar.
Your welcome letter shouldn't be like a plain slice of bread; it should be like a hot, buttered biscuit with some gravy on top. You want to draw in new PSAs, right? You've got the ingredients, now all you need is some seasoning.
