Webinar service....

Pappy,
... depends what you feel is inexpensive ... I have used gotowebinar.com for 2 years and never had a total failure ... and a couple of times only with garbled speech and that sorted itself out after a reboot ...

Seems that the problems were with a slow link on my side as a host (through mobile link) with Skype running in the background.

What is nice is that people can also phone in internationally to local numbers in their countries. So their costs are low and it allows people to connect that want to use a phone and are not at a pc.

I have been a guest on some other systems and have not been impresed enough to change ...

If you just need a dozen connections, use Skype.

If you host webinars with poor speech quality, you will piss off the listeners ... and that might cost a lot more than the monthly fee ...
