As a suggestion, you may want to post this invitation may be also in other C&C sections like Ancients and such. Actually this brings me to an idea and suggestion. I believe it would be really useful to have a single forum or forum section common to all the C&C sections, for tournament and similar announcements. I do not know if it is even possible, but for sure it will be easier for all the people to follow all the upcoming great tournaments.
Or may be there is a way to be subscribed to any such forum, but than again if that new person is not a member of the new section like Medieval, TGW etc. then they might miss it.
