Either we can sort this out like civilized users, or this can turn into a pissing contest. "Serieses" is not a word. 'Series' is one of those words whose singular and plural forms have no difference spelling-wise.

Should you need further convincing, you can always look it up for yourself.

Edit: Sorry if this came across as condescending. Not my intent, but this "Serieses" category has been irking me for the longest time and this was the last straw.
