Welcome to all New Topcoder Members!
I notice several new members who've introduced themselves and joined in the past few weeks!
A big welcome to all.
First of all, I would like to invite everyone to our Discord server, where all the community action is: https://discord.com/invite/topcoder (joining the Discord server is highly recommended)
If you have nothing to say there immediately, you can posts memes, educational links and general suggestions there as well 
In terms of Topcoder's offerings to our members, we have three options:
1. Challenges: https://www.topcoder.com/challenges
2. Gigs: https://www.topcoder.com/gigs
3. Competitive programming: https://www.topcoder.com/community/arena
