Wow! Good responses. Thanks!
Let me address them as best I can: (One reason to come to InVision is this editor.)
Joel: (Not with your same numbering scheme)
My understanding, which is supported by Jim's response, is that if you want to run on their cloud you have to go with their conversion. We are motor-heads, not IT guys, although I retired from IT and have several good ones on the forum - at the present time. But people come and go on the forum over time and I don't want to count on having an IT guru help me do self-hosting. I think I'll be better off running on their cloud and let them do the IT things. The annual cost of going that way actually looks to be cheaper than the one-time purchase and annual maintenance fee plus the AWS charges
Glad you liked the comparison. It really helped us, mostly me, think through the issues. And there are issues.
I've wondered about using the rest of IPS for other things. Some of the guys suggested that, but our main need is to get a stable forum platform. We can address the other issues later. But it is good to know that the capability is there. Weebly is stodgy and a pain, but it works - for now.
Sonya: Nabble will shut down at some point. And even while it is up there are lots of problems. The joining process is broken/poor, you can't email between members anymore, the orientation of pictures is awful and causes handholding with all newbies, etc. So if we are going to have to move at some point why not move now and enjoy the benefits of a better platform?
Jim: That was my understanding. In fact a friend is a specialist in the migration area and was very interested in doing it for me for free. But then we found that we'd have to run on someone else, and after totaling the price of the purchase and annual maintenance we decided that it isn't worth it - if we can come up with the money for the migration.
DawPi: If you want to contact me behind the scenes to enlighten me on your services I'd be interested.
