Hi Skumpic and welcome to the forums.
That's ok - I can understand what you're saying perfectly
There are more ways than one to help the "community". Help out on the forum here (helping others set up, giving your thoughts on voip etc etc) or writing a review of a piece of VoIP hardware that you own. That all adds "value" to what we do here.
We are currently considering a PayPal "donation" option, although we're undecided about it. Our true aim was to create something that didn't involve the use of "cash". Given the large number of non-UK users that we seem to be attracting, we may have to introduce that option.
We'll keep you posted on that. In the meantime, like I say, you can contribute in more than one way. If you're not directly generating minutes into the pot however, I would suggest that really you should keep your useage down very low in any event.
If you really need outbound VoIP as a more permanent solution, you will probably need a "proper" VoIP provider.
Hope that all makes sense!
Dean
