yes they can post on ihub . they are also aloud to post here the difference is on ihub they don't have to give them the respect they have to give other posters because they are part of the company. but here on investors hang out you have to give the ceo of a company the same respect as other posters get or you can get hit with not following the tos and get hit with personal attacks on a poster here they are considered a poster just like every one else is.
