Welcome to all our users. Since quite a few have signed up today, I urge you to read the Site Usage posts, and I would like to remind people that the forum supports posting images, and very nicely. If people have thought a certain social media site is better for that reason, we now offer an even easier interface to use.
Discourse is a mailing list in parallel with the web forum. Again, please read the informational posts about this.
Finally, if people have any queries, message me here (PM me). [Don’t clutter the topics with questions about how to do things.] I am always ready to assist.
