I don't want to be too negative or elitist here, but I have to say that usually one can identify the self-promo posts very quickly.
It is fair to say that hobbyists have a bit of money, or they wouldn't be hobbyists.
Rightly or not, this money can normally only be obtained by persons with a certain amount of linguistic skills.
Even the foreign hobbyists amongst us can be identified by their grammar and spelling.
So when a poster repeatedly spells their as thier, I have my doubts about the post's authenticity.
Just imho...
