Change owner of Catalyst IT

Hello.

We, Catalyst IT, trying to organise and clean up our Drupal presence . As part of that we have changed the ownership of the company page in #3164936: Please transfer ownership of https://www.drupal.org/catalyst-it to the new comms person UID 3654464, but later decided to re-purpose that account (UID 3654464) to be shared to not have ownership issues anymore. When I tried to change the name of UID 3654464 to "Catalyst IT" today validation failed saying that the name is already taken. I found the user Catalyst IT (UID#842188) . Which looks like the previous attempt to create a shared account.

We would like to know if it is possible to:

1. change UID#842188 email to the one of UID#3654464, so we can reset the password
2. tranfer ownership of https://www.drupal.org/catalyst-it to the UID#842188
3. UID#3654464

We have couple projects that we would like to contribute and be owned by the proper shared account.
