Welcome, proud owner of an openVolver. It will probably take you around 2 hours to solder your blinky. Before you start assembling your openVolver, let's make sure you have everything you need.
YOU WILL NEED:
A soldering iron. Any iron will work, though a smaller tip will work better. If you have a big battleship style soldering iron, you may want to hit the local Radio Shack and find a smaller tip.
A wet sponge to clean your soldering iron with.
Solder. Just about any solder, including rosin-core or silver-bearing, will work just fine. Do not use acid-core solder.
nippy cutter to trim leads with. A pair of dykes will work but not as well.
Solder braid in case you make an error.
A magnifying glass to check your work with.
Hot glue or double-sided foam tape.
A clean, well lit working space away from cats.
A nasty old toothbrush

Soldering isn't hard to get the hang of. The key thing to remember is to heat the joint, not the solder.
First, make sure your iron is tinned. This is done by melting a bit of solder onto the tip of the iron and wiping it on the sponge. It should be shiny and silver. If you cannot get the tip of your soldering iron to become shiny and silver, you may need a new tip.
Hold your iron on the pad (the shiny part of the circuit board) where the lead comes through. Hold it there for a few seconds to heat the joint up. Then, when it's good and hot, touch the solder lightly to the joint. You don't need to use a lot of solder to make a good connection. Your solder joint should look like a tapered volcano. If it looks like a volcano with straight edges, that's OK, but you can use less solder. If it looks like a ball, you are using too much solder and you may not be getting the joint hot enough.
