[Plugin: Visitor Maps and Who's Online] Change the name of a widget – Change the Who's O

Changing the name of a widget – Change the Who’s Online to local language

I am someone who have use this plugin for a long time, than suddenly it stop working – I abandon it but now after almost 6-7 month I am now again using it – but I have always one idea – to change name of widget which appears on my blog – simply it not fit into everything else with English language name – Who’s Online – I appreciate people who make It, but that customization is kind of necessity – I will like to know is it possible to change it and where – I only want to change that because I don’t want to use it on “my language” bit only to change name of widget on my blog – Thanks in advance –
