This job is to go through the 240 posts on this site: [url removed, login to view] and put each post into a category as well as add tags to each post.
You will need to look at the post and decide what category it fits into.
e.g. if it is about solar power the put it into the "Green" category.
You will be required to organize, add, or remove categories based on your best judgement. For example if you find that there are a lot of posts about "Spain" but the only category is "Europe", then you could add the "Spain" category and move a lot of the Spain related post from "Europe" into the new "Spain" category. Or you might decide to remove the "Europe" category altogether.
Each post should have three to four key words that represent the overall theme of a post. For example a post about a restaurant during a trip to Spain might have tags "Spain, Travel, Food"
the best way to do the job is to look at a lot of the posts and get an idea before jumping in.
