Totally agree about the newspaper ads.
I had a few dissolutions on the go last year. I had written off to the Revenue to get the Revenue clearance letter. One of my nice "helpful" colleagues decided in their wisdom to help me and stuck all the newspaper ads in. When I came back, no clearance letters because a couple of the companies had old returns outstanding. So ads ended up having to be replaced. Cheapest papers I find to place the ads are the Sun or the Mirror. We used to use the Examiner for our ads, but very expensive.
Do not place the newspaper ad until everything else is in place and get it into CRO straight away in case there is a problem with the paperwork.
Its all very well saying its easy, and it really is, it is to me because I do it on a daily basis, but like everything else, if you dont know what you are doing, it may end up costing you.
