I read somewhere that the IRS has imposed an IRA One-Rollover-Per-Year Rule – is there such a Rule and how does it affect me?

Under IRS Announcements 2014-15 and 2014-32, beginning in 2015, taxpayers can make only one rollover from an IRA to another (or the same) IRA in any 12-month period, regardless of the number of IRAs owned. The money in the taxpayer’s IRAs, including SEP and SIMPLE IRAs as well as traditional and Roth IRAs, is lumped together and treated as a single IRA for purposes of the limit. Since most people use rollovers to move their money from one financial institution to another, the better practice – and one that avoids this confusing new rule – is to arrange for a direct transfer from one financial institution to another, which may be as simple as checking the correct box on a form. This way you never take possession of the funds, as a result of which the transfer isn’t considered a rollover at all, and the rule does not apply. There is no limitation (at least as of the time this is being written) on the number of direct transfers as you can make.
