I know sometimes people like the one-on-one buddy approach, and it's all good!
However, I just wanted to point out that there are a bunch of accountability challenges, and daily chat threads, and all sorts of places where people talk about their plans for the day. Wasn't sure if that's the kind of accountability you need, but I wanted to mention it in case it might work for you =)
As a side note, people might not be able to PM you, yet as you have fewer than 20 posts. Not sure if you also need to be here 20 days for PMs to open up for your account.
Hope you find what you're looking for!
