I do say in my adi work part time but you know punters dont read the ads half the time. So when i get home from work i reply to all txtsand messages saying when im free next week. So i think a one or two day or 3/4 day ad would fit wth my circumstances better xx
I think you'll still get messages about and on the days when you aren't working, many men save numbers and contact details, but it may help reduce them.
The main impact will be reducing your costs, but as we've seen in the past when VS reduce the time for adverts, they tend to not reduce prices by very much you might find the shorter ad isn't much cheaper, or turning it on and off ads up - every little helps though.
I also hope that their moderation system can cope with it, would be nothing worse for you to turn it on for 1 day, VS don't put it on for a few hours, then suddenly decide they don't like your pics, spend your day trying to get it back on!
