Jack,
Thanks for the clarification. We don't have a way to do that right now, but it's an excellent idea. Honestly thinking about it, a lot of the different code pieces are already in JFBConnect in different places, it probably wouldn't be overly difficult. We have some code to fetch a user's friends, we can easily look up to see if the friend is in the system already, and adding the connections in Joomla is just a few lines of code.
One of the biggest issues would be speed.. if the user registering has 300 friends, that could take a little bit of time to import those friend IDs, do the lookups and make the connections. We're not talking minutes, but maybe 30 seconds (complete guess), which would obviously be a bad experience for the user. So, that's the main aspect that could be difficult. I could be very wrong, and maybe it would be a quick process (a few seconds), but that's something we'd have to investigate further.
If you know code or have a developer, we could gladly help you get started on things. If not, as mentioned, we liked the idea and it's likely something we'll be looking into for v5.2 in October.. but I can't guarantee when it would be available.
Thanks again for the feedback, and if you have any comments, let me know.
Alex
