oh ok great so i dont have to worry.

On one occasion my own installation of simplex stopped working, even though i left the default servers.  I had to back up my database and re-install the app....same servers were present though and then it just worked lol...very strange.

Should i be running my own simplex server on something like Start9 OS, and if I do, will my existing contacts still be able to message me without updating their servers?
