I visited The Portable Freeware IRC channel at freenode but there wasn't a living soul there.
I will also publish my Tox ID:
C993DF91A00DF065186E04711316F27AFF106830EDB9765C61DC3EF6DA1D5F4F3D84EE36BE16
If you don't know you can register your Tox ID at the public list-
Tox ID Service, it serves as user lookup, just hit
sign up.
If you are using qTox or Isotoxin, back-up your profile (name.tox for qTox and name.profile for Isotoxin), if lost it is unrecoverable. Isotoxin allows to export your profile- right-click on your Tox ID and choose Export, thus it can be used with qTox, screen-shot below.
