As James has noted it would be best to introduce yourself properly before asking to become part of the family.
Or you can just figure we are a bunch of old farts here. :]
Well, I believe starting his first post here seeking technical information is OK. And would politely ask for an introduction - or better yet introduce myself in return.
At least his first post here isn't a for sale ad!
So - Welcome Mr./Ms. Lukasz and please introduce yourself.
And congrats - you have Mahle forged pistons.
Cheers
