There are two opposite sides of the allowable option to modify post title inside threads:

Advantages:

• OPs or the other posters are able to modify post titles to mark changes of projects (developmental upgrades, future plans, ie.), campaigns (Open, CFNP, Full, ie.), etc.

Disadvantages:

• There are many different post titles inside one thread, from OPs, or from the the other posters, that might mislead new guests.
• It will probably cause uncontrolled trollings, ie. that is what TECSHARE asked for changes.
