“分配权限”是指在 wiki 软件内部授予用户额外权限（或收回这些权限）。这是通过在 Special:UserRights 页面中，添加用户到含特殊权限的“组”完成的。不过，首先需要注意的是该操作本身需要特殊权限！
The Special:UserRights page allows you (if you have access) to set which groups a user is in. A common task would be to put a user into the 'sysop' group. This will grant the user various extra rights, such as deleting pages, and blocking users. See Help:管理员和权限 for more details.
Obviously giving a user such rights implies that you trust the user, both in terms of being non-malicious, and also as somebody with sufficient competence in using the wiki software, and in dealing with the wiki community. People hoping to become sysops should read Help:管理员和权限. However it should be noted that actions of a sysop user are (almost) entirely reversible, by other sysop users, and so it can be a good idea to dish out these extra permissions to a number of users in order to
- spread the workload of day-to-day sysop operations such as blocking vandals and deleting pages.
- make things more democratic, and decrease any perception of a single dictator running the community
- allow competent users the power they need to make progress with wiki refactoring.
- reward valued contributors/community members
If you have many sysops, you may start to need documented processes governing their actions. e.g. when should a page be protected versus leaving it unprotected? You may even reach the point where you need a documented procedure for deciding who gets to be a sysop, and who should have their sysop rights revoked. To manage all of this, you may wish to promote several users into the 'Bureaucrat' group (a smaller number of your most trusted users) to spread the workload managing the promoting/demoting of sysops. On some large wikis, users are voted in by other users before they are granted extra permissions, and sysops have their rights revoked by a committee who investigate accusations of misconduct. Such processes are unlikely to be necessary in anything but the largest of wiki communities.
