Please read the Regions - Intro page for a brief description of the 'rivers' and free association aspect. For those who like to discover their own introductions, then basically this page is the comments channel for the European continent. If you live in this continent then post on this page whatever you think is interesting for yourself and/or others.
Though the menu indicates more continents, at the present only North America and Europe are online. The reason for this is for me to get a basic idea of rate of participation and other aspects. Until the other continent pages are up then those in other continents can post in these too.
There are no main questions or topics such as usually seen in other comments formats though you can ask your own question and see if others answer. Make it an expression of 140+ characters or several paragraphs — your call. At the present, photos are allowed but please do not embed videos though you can supply a link to them.
That's the briefest I can make it here, Again, I suggest reading the above-mentioned Intro page to get a good idea of the premise and other details such as guidelines, possible developments, etc. As for participation, I can do some promotion of this website via social media and other ways but the best promotion is by those who participate telling others.
For those who wish some background music, the "Radio" page has several stations from which to choose. Please note that the page has to be in its own tab so as to be heard while viewing other pages.
