I know I am a trusted member of this Forum, have been for years for anyone that is new, and wanted to throw this out there.
I am doing Tennis DFS, and I am posting this because this is no tout service or anything like that, rather if you are interested, then let me know via PM.
I help run a Fantasy DFS site on the side, and we are in Slack for our channels and what not. We have a free tennis room, as well as a premium room, not too expensive at all.
If you play DFS as is, and are interested in not only gambling to win on Tennis as we do here but also giving Tennis DFS a try via Draftkings, let me know. If not, no big deal, just wanted to throw it out there.
