Over the years, members of the community have been willing to gather over some chat services in order to have a direct way to communicate and exchange around Construct Classic and Construct 2.
Historically the IRC channel "#construct" on the server irc.esper.net (irc.eu.esper.net) has hosted some of those conversations.
Since, other channels on different servers/communication tools also were put in place by the community.
Here is a non-extensive list of those. In no way are those channels officially endorsed by Scirra, they are user-managed, filled and moderated.
Use common courtesy and if you have a question, don't expect an answer in the second as it depends on the user's availability on those channels.
If ever you start your own server/group/whatever communication mean, consider posting in this topic.
But before you do, ask yourself if it is not worth trying to join one of the existing channels first.
You can also find some Facebook groups (possibly in different languages than English). You can find some URLs to those in the "Non-English communities" topic.
Some of the services/channels listed may not be available anymore, as mentioned, it is all user-managed.
Moreover on top of the actual forums you may also want to check the Construct2 Sub-reddit.
It is not exactly a direct messenger style of chat but still can be a good way to communicate with other users as well.
