Maybe I'm a bit thick, but I still do not understand your position, Krona...
Did you build that T-28..? If so, why don't you make it plain? I'd be very pleased to hear about your experiences with this apparently bear of a kit (from what I've heard from other modelers)... If you did build it, you could post the pics without the advertising that surround it, no? Everybody else seem to do it that way.
Are you instead trying to get people to join in that discussion forum/group? If so, why not simply advertise it for what it is? There are many people in here, including myself, who have 'advertised' other forums, other discussion groups, chat rooms, websites.
By 'advertised', I mean 'told us' about those other 'places'. Your original post takes us to what is basically a e-shop. Two links on that page bring us to the particular product, with practical ways to order and pay for it...
When I post pictures of my Revell Concorde, I do not add a link to Revell nor Hannants... Now when people ask me (they haven't so far!) where they could buy that Concorde kit, I feel I can add the link to Hannants, or Squadron,..
This forum is not a billboard, and thanksfully, 99.9% of the members understand that, because if they did not, we would be submerged by advertising here... I alone could very well send links to all the new releases from the handful of companies I sometimes work for... I'm sure it would briefly benefit those companies (before I get kicked out by FSM), but I feel this is not the right place...
I think you should respect the way this forum is being run.
