Is there any way that a client can post muiltiple ads in the same transaction?

No, there is not. Our next version (see WWC 4.0 thread) will work on a credit based system, where users buy credits, and basically have an account with the script. This will address this feature easily enough.

Ok thanks. Any idea of how long it will take for the next version? Am I talking at least a year? If so I guess I'll have to work it out myself as I need it asap and cannot wait that long. Or have you any idea of how I can cobble something together that'll do for now as I can't be the only person who requires multiple ads in one transaction?

Thanks again

Well, it will not be a year but we are a bit early in development and it will be at least a couple months.

Actually, you are the first person to bring this up that I can remember. I really do not know of a way to do this with the current software.
