Hey tradesmen,
I'm pretty sure if you check the charter you'll see you must state any interest you have when recommending a particular company or person, site etc.
I'm assuming you have an interest in that site due to your username and the fact I've seen you recommend it about 5 times now out of your first 20 posts.
By the way, I've also seen you give useful help to people so I'm not getting on your back, just stating how it works around here. Don't think there'd be a problem if you declared your interest when recommending (though I'm not 100% on that).
