Hi Coppo, myself and Will set up both the same accounts on Motorhome Fun to do the same as we're doing here. The feedback benefits us and hopefully our advice can benefit you guys. However Motorhome Fun got a bit cranky because we've used company names as our User Names, it was declared advertising lol. We haven't bothered signing up with alternate names yet.
TBH "Fun" are probably correct to stop you posting promotional material in the forum, if you want to advertise your products then you should pay to do so.
Having said that, to prevent you using your trade identity as a user name is a bit silly. On MHF we prefer traders to use their trade identity, that way members know they're getting advice from a trader, not an independent party.
The forum owners here seem to be reasonably relaxed about posts from traders that inform and educate members (information about new products, safety updates, special offers etc.) and they welcome expert advice to any queries that members may have about your products. However they will not accept blatant promotion or direct sales from traders unless they pay to advertise.
My advice therefore would be to maintain a presence, answer any queries from members and inform us of any product developments without directly promoting your products or offering anything for sale. If you do that you're likely to avoid being banned or having posts removed.
