In all honesty, I think that there is nothing wrong with having ISO's on the regional boards. Posting one on a local board is good , as long as you know what to do. I always laugh when I see some scrub post a last minute ISO with nothing more than something along the lines of "looking for a fun time tonight in Raleigh/Charlotte/etc....
A hobbyist usually posts an ISO for one of two reasons:
#1: the hobbyist posting the ISO is an out of towner who's coming in to town in the eventual future ( or he's in town already and was too stupid to do his homework). The hobbyist is looking to see who is available, and out of those available who would be a good fit ( I.e. Price range, incall/outcall, special requests, etc...). Usually the hobbyist posts well in advance, 1 month give or take.
#2: the hobbyist posting the ISO is local who has an open date in the eventual future. In this situation, the hobbyist is looking for a quick way to see who will be in town on a certain future date without having to go from website to website to get his homework done ( I love date-check, but sometimes ladies won't post until the day before they arrive). The hobbyist is looking to get a booking well in advance for both his and the providers benefit.
For the newbies reading this: if you're going to post an ISO and hoping for a response (or more), the key elements for a good ISO are timing and detail:
Timing: as soon as you have a date open up for an appointment, go ahead and get to work on what you're looking for in your date ASAP.
Detail: when posting as ISO, details are crucial. a basic ISO post includes the following: when you will be in the area, the time of day you wish to have your appointment, the location of the date (incall/outcall), and the length of the date. If you're looking for something more specific , more details should be included ( I.e. Clothing requests, fetishes, age specificity, etc...).
If you just follow those steps, you'll be sure to get a response (or more) from numerous. Everyone on this board has seen their fair share of good and bad ISO's.
