Topic: Have spaces in tags.
Right now, we can't have spaces in tags. Say, when you want to write a tag which contain two words or more (like a name), the spaces will be removed.
For instance, I wrote: This Is A Tag, Another Tag, A Name, Two Words, More Than Two Words
When saved: ThisIsATag,AnotherTag,AName,TwoWords,MoreThanTwoWords
I don't know if this have any impact on the SEO, but I think it'd look better when we can have spaces in the tags. It's pretty rare to see the tags not able to have spaces in it.
