Did I just ruin my Steam Boiler?

So I have a Weil- Mclain SGO Series 3 Oil-Fired Steam Boiler, to get it ready for the heating season I decided to skim it since I had lots of issues with water hammer last year due to new piping crud and oil that had collected at the bottom of the boiler. Figured it would be good give a skim to get a little more of the crud out of it before it would be going all the time. So I started it up for the first time since last march, no real issues, except that when I started to fill the boiler with water to hit the skim piping the glass gauge water wasn't moving at all, filling and filling more than I normally would, all of a sudden the water in the glass gauge jumps up and the pipe immediately starts spewing water. Ok, no biggie I back off the water flow and do the skim.

Now the skim is done, i'm at the bottom of the boiler, releasing water to bring the water line in the glass gauge down to where it needs to be. I'm emptying water, and more water... and more water and the gauge is completely full. I know have emptied more water than I think is right and to be honest the flow of water is appearing that I have almost emptied the boiler. So i stop and turn one of the knobs at the bottom of the glass gauge and all of sudden all of the water just shoots out of it emptying it. So i did empty most of the water from the boiler, so i fill it back up, this time the glass gauge is moving and i fill the water line to the correct level.

So the question is, did I just totally ruin my boiler by basically emptying it of its water? Obviously the boiler was not running during this whole time and I will probably not turn it on again for another week or so. I've heard that replacing the water to much in the boiler is bad as well as other bad things that can happen if the water is not right. Any suggestions of things that I should do or is it going to be fine and I shouldn't worry?

Any help would be much appreciated!!!

it'll be fine
Steam boiler deal with a lot more fresh water than hot water boilers do, so they are better built to deal with it.
We often install automatic blow down valves on steam boilers that dump so water as you did.
