Slack link broken and I would like to contribute

[spartanjoax]

Hi everyone,

I am working on a continual learning regression problem that uses multimodal data. I have forked the repository and created my own regression metrics (R2, RMSE, and forgetting for both of them) as well as worked on my open issue #1678 to be able to handle multimodal data in the form of dictionaries.

I would like to contribute these solutions to the main branch, and would like to ask how to become a contributer. The Contribute page of Avalanche has a broken Slack link, so I cannot join and mention it there. Looking forward to hearing from you.

Best regards,
Joaquín
