What has been done so far

1.) At the moment the Community TESTNET condenser is pointing to the official Steem TESTNET blockchain at https://testnet.steemitdev.com

You can visit the official Community Condenser website here https://steemtest.com/. If it states that "HardFork Testing - Steem TESTNET Active", then you can send test transactions and they will be only visible on the Steem TESTNET

If you try to make transfer Steem, the wallet will show your balance in TESTS variables:

2.) Our main goal is to improve Steemit and help with the testing.
The folowing issues were submitted to the official Steem github and Tinman github

https://github.com/steemit/steem/issues/3067 - submitted by Hive account@yuriks2000 about Condenser error

https://github.com/steemit/tinman/issues/151 - submitted by Hive account@bobinson about MAX_RETRY not being defined in Tinman

https://github.com/steemit/tinman/issues/153 - submitted by Hive account@bobinson about better error handling

We copy the links to bugs reported in our discord channel Hard Fork Testing in bugs-reported section.
Would be more than happy to see you join the Community testing network.

What are the next steps:

Install "Steem Keychain" as advised by Hive account@aggroed, with the help of Hive account@yabapmatt to further secure keys when testing
Set up the Official Community TESTNET using Tinman
