I don't think there is anything to be gained by using the Autralian or any other Hearme site. It did appear for a while that the oz site was more stable but it was just co-incidence. As far as I can make out, the problem lies with Hearme (the chances of it being down to one site were low anyway, in fact I can't even see why it should make a difference - just wanted to try it just in case).I have a horrible feeling that Hearme don't care about the free services any more and the service is not going to improve. Hearme have already hidden the voice creator pages anddon't seem willing to answer technical support questions.
I don't know how long we give it to see this run of problems continue but I think that the time has come to consider/ evaluate alternatives. PalTalk looks favourite to me. They seem to have improved since the last time I looked at them and allow the creation of a permanent room which can be moderated.
The set up is more complicated than Hearme as to use a permanent room requires an admin to open it - could give everyone the admin key though...or use temporary rooms. I have joined a country sing around for the last 2 nights and the set up seems a lot more stable than Hearme.
