Kubo, I know most of us are using multiple ym accounts. Here's my share of editing registry, no more installation of 3rd party programs!
1. Annoyed by the ads? Start -> Run -> regedit Navigate to: HKEY_CURRENT_USER\Software\Yahoo\Pager\YUrl Add the following string key: `Messenger Ad` [wihtout the quotes!] with the following value: "*".
2. What if I have 2x accounts? Start -> Run -> regedit Navigate to: HKEY_CURRENT_USER\Software\Yahoo\Pager\Test Create a DWORD key with name of `Plural` with a value = 1
If things seems to be not working, restart ur pc for the changes to take effect!
