If CE can spell X, I will Y

"If CE can spell my username, I will close my account ~ Many Users"

If CE can spell X, I will Y" is a type of topic consisting of a challenge to CE. The challenge usually is to spell a certain word or phrase, either the TC's username or some other random word(s) of their choice. The TC then implements a list of rules to prevent CE from cheating (loopholes on either side are generally considered by CE to be invalid). Keep in mind, many people who make these topics rarely keep their side of the bargain. Also, note that Night CE is a lot better at spelling than Day CE due to slower activity.

Rules
The rules usually consist of the following:


 * One letter per post.
 * You must start over if the sequence is interrupted.
 * TC's posts do not interrupt a sequence.
 * No double posting by the same user (includes alts).
 * Same time posts are still counted in the sequence, in the order they are displayed.

Less common rules can be:


 * No signatures.
 * Case sensitive.
 * Punctuation and spacing are ignored.

Strategies
CEtizens have developed certain strategies to successfully complete spelling tasks. General tips include refreshing the page before posting a letter (to check if others have posted) and using GameFOX's "Post Message" feature (to skip the "Preview Message" page). More elaborate plans include creating a "sign-up list" through which users volunteer to be responsible for posting a certain character. Furthermore, sneakier tactics include using secret alts to post consecutively.

Trolls
Trolls also have their own strategies for foiling the efforts of other users. They may deliberately post the wrong letter, sometimes one not even found in the specified word (often 'q'). They can also make subtle changes to sign-up lists to confuse their peers. The TC of a spelling topic can also troll his or her own topic by failing to deliver or breaking sequences with their secret alts.

Notable incidents
In February 2008, Butters 1188 became infamous for failing to close his account like he had promised when users successfully spelled his username. Even today, whenever he posts, users will tell him to close his account or post jokes about his failure to deliver.

Another noteworthy instance of success was when Night CE spelled "Eyjafjallajokull" three times for a user.
