That’s great, but there needs to be some way for people to get to that from either an organised activity, a task manager project or a series of changesets, and also the only reference to “Arroio” on that page does not contain OSM contact details. Three individuals are listed; one (you) has an email address listed but not OSM information, the other two have nothing.
If someone wants to know about new organised edits they should be able to add the OEG activities page to their wiki watchlist. They shouldn’t have to add literally every other link from there as well.
