One further piece of advice. Start small. I've seen many new guys on GTP who haven't run series before try to get out of the box with 10+ dates on a calender, all kinds of big plans and everything falls apart before they even get started or partway through the season. The most successful Race Directors on GTP have established reputations and lots of repeat business because they are know for being consistent, on time and for enforcing rules and regulations. They can announce a 10+ race calender and people know they will follow through with it.
IMO the best way to do this for someone new to GTP is to start smaller with a 4 or 5 race championship for example. Put everything you've got into it, start everything on time and on schedule, work on your preparation for as long as it takes, study other race series to see what they do etc. When you make your first post announcing the series it should be completely ready to go, not just a quick blurb one puts together at the last minute. Have someone check your spelling, grammar, sentence structure etc. Have someone look at the graphics and layout. These things are subtle but important to some people. It shows how professional you are and what your approach will be.
Being prepared and ready to go tells the community you are serious and are willing to do the hard work it takes to make a series successful. There's nothing worse than being a couple of races into a series and discovering it's poorly run, or the RD has a lousy internet connection or the RD isn't always there when he's supposed to be there. You have to remember that the drivers are investing their time and effort in practice and getting ready for each event and it's incredibly disrespectful on the part of an RD to treat their time and commitment with contempt by being wishy washy with rules, start times etc. Most decent drivers will not tolerate this kind of behaviour and will abandon a series as a result.
I'd also suggest getting to know and using the
GTPlanet OnLine Racing (OLR) Rules & Guidelines as a basis for your race series. They really do work to promote clean racing if everyone follows them and provide a clearly understood set of guidelines for on track behaviour. Rules like, "
be clean and respectful" don't work in real life, everyone has a different definition of "
clean"
