Several languages are represented because these blogs are scattered all over the Earth. We have writers from South America, North America, Eastern Europe and Western Europe. (If any of our readers from South Africa and the Pacific region know of any sites that we should add, please contact us.)
Our Meetups map shows that a lot of groups are now forming. We are working on a Meetup guide to help you all organize effective gatherings. I'll report on that here when it is finished. My experience is that the first meeting is the most difficult and frustrating, because getting the word out initially is one of the hardest things to do. Once you have a few people, word of mouth kicks in and the second meeting happens much more easily. So if you are still waiting for that second person to sign up so you can kick off your group, be patient. These things take time.
One group that has existed for a long time is the Temple of Venus Genetrix in Nashville. They have scheduled a Feralia for February 19th and Quinquatrus for March 19th. They list 48 members, so I expect they will have a good turnout for these events.
There is a group now forming in Malibu that has scheduled a Parentatio for February 13th.
On the same date, there is now a meeting scheduled for the new group in Warsaw, Poland.
There is a meeting planned in Madrid for April 21 - the "Birthday of Rome".
There are a number of festivals in April, including the Vinalia, so if you don't have anything planned now, I suggest planning for a date in April. The 21st falls midweek this year, but the following weekend would be a good choice.
Finally, work continues on the new Cultus Deorum site, where we are now working on "Beginners' Guides" in a number of languages. I hope you will visit there, already there is a good deal of useful material, and it is being added to almost daily.
