Hey there Gilbert...
As your ad was just 'unpended' (made viewable to the public) yesterday, I would be very surprised if you had gotten any answers to it on the 27th...
As with any job advertisement, it will take time for replys to start coming in. Also, as Asmo pointed out, pickings are often slim
Unfortunately the Recruitment Depot isn't a magic bullet... just because you've posted up an advert doesn't mean people will come beating down your door...
The last advert I put up only garnered two replies... however that was more than enough to fill the position I needed
The best way to recruit in the OFP business is by getting to know people. The way I would recommend is to do some beta testing for people... what you test is up to you (missions/addons/experimental contraceptives... er... never mind that last one ;D), but the key is to get out into the community and meet people. Then you can start calling in favours
Anyway, Good luck with it and remember: Good things take time...
